Triangle Congruence Geometry Congruence Triangle Congruence Questions What do AAS, SSA, SAS, and SSS stand for in geometry? Why can't you prove triangles congruent by using side-side-angle? Why does the sss postulate work? Question #42ce6 #triangleABC# is isosceles, where AB=BC. If #m angleA= 5x+ 30# and #mangleB= 2x#, then how do you find #mangleC#? Question #2ac09 Solve for x? Show the equation you used and your work. The #DeltasABC# and #FGH# shown below are similar. Find #bar(FH)#? Given the 2 sets of figures below, are the pairs of triangles similar for both set a and set b? Why or why not? What is the similarity statement and the scale factor? Properties of triangles?
